ANCHORAGE, ALASKA — Jurors will hear opening statements Tuesday in the trial of a Coast Guard civilian technician charged with killing two co-workers workers in Kodiak.

Federal prosecutors say 63-year-old James Michael Wells nearly two years ago dodged direct surveillance cameras and shot 51-year-old Richard Belisle (BEL’-eye-ul) and 41-year-old Petty Officer 1st Class James Hopkins at the communications station workshop where all three were employed.

Prosecutors say Wells’ had feuded with his younger co-workers and was unhappy that his authority in the shop was ebbing away.

Wells claims his truck had a soft tire and that he drove home to change it when the men were killed.

Defense attorneys say prosecutors have no physical evidence linking Wells to the crime.
